Hello My 4 cly Vue has engine light and code PO449. I do not have the meters or tools to troubleshoot this the right way. Should I start by replacing the vent valve? Or purge valve or both? My VUE mpg, appears to be very bad.. I just bought the car and shortly thereafter, the engine light came on. my assumption is the vent valve? Also, having trouble trying to find a video that shows wh2008ere and how to replace on saturn vue 2008 XE 4 cyl.. thank you
Hi there
Based on the code, the place to start is with the vent control solenoid. It's mounted to the charcoal canister under the car. Here is some info on the code.
